Fig. 6

a Principal component analysis (PCA) comparing conformational spaces of free and bound states. The PCA model was constructed using the MD trajectory of free AflR-DBD and applied to DNA-bound AflR-DBD states. b Porcupine plots illustrate major conformational motions on the free state along PC1 and PC2. c, d DNA binding-induced changes in conformational dynamics along PC1 and PC2. e Changes in residue centrality upon DNA binding identify key communication hubs. Red dots indicate increased centrality, while blue dots represent decreased centrality.
